यदि (n(U)=55), (n(A-B)=14), (n\(A\cap B\)=9) और (n(B-A)=17) है, तो बाहर का क्षेत्र कितना है?
If (n(U)=55), (n(A-B)=14), (n\(A\cap B\)=9), and (n(B-A)=17), what is the outside region?
Explanation opens after your attempt
A. (15)
Concept
The union is (14+9+17=40), so outside is (55-40=15). The outside region is the complement of the union.
Why this answer is correct
The correct answer is A. (15). The union is (14+9+17=40), so outside is (55-40=15). The outside region is the complement of the union.
Exam Tip
संघ (14+9+17=40) है, इसलिए बाहर (55-40=15)। बाहर का क्षेत्र संघ का पूरक होता है।
